HERMAN W. KOERNER, OF WAUWATOSA, WISCONSIN.

METALLIC SHIN GLE.

T0 all'whomz't may concern: 7

Be it known that I, HERMAN W. KOERNER, a citizen of the United States, residing at the town of Wauwatosa, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Metallic Shingles, ofwhich the following is a specification.

My invention relates to improvements in roof coverings.

The object of my invention is to provide a practical and inexpensive substitute for the ordinary wooden shingles :heretofore used, this being accomplished by designing a metallic shingle of a form adapted to interlock in water-tight relation with like shingles with a minimum over-lap.

In the drawings-Figure 1 is a plan view of a fragment of a roof, showing a set of shingles embodying my invention applied thereto. Fig. 2 is a sectional view of a roof covered with shingles embodying my invention and showing the ridge or apex member. Fig. 3 is a detail view of the blank from which the shingles A are made with the folding lines dotted. Fig. 4 is a sectional view taken on line 09-01: of Fig. 1. Fig. 5 is a plan view of a modified form of shingle embodying my invention. Fig. 6 is a detail sectional view, drawn to a transverse plane indicating two shingles of the type shown in Fig. 5 in interlocking relation.

Like parts are identified by the same reference characters throughout the several views.

Each of my improved shingles comprises a sheet metal member A, which may be slightly arched as shown in Fig. 2, or flat as shown in Fig. 4, where it is designated by the reference character A. The member A is preferably diamond shaped or hexagonal in form, said member as illustrated in Fig. 1 being diamond shaped, while in Fig. 5 it is substantially hexagonal. Along two margins which diverge from one corner, it is provided with flanges which are reversely folded along two parallel lines a, a, to form I an inturned portion B underneath the margin of the member A, and an outwardly extending portion C whichprojects from underneath the member B as clearly shown in Fig. 2. The outer margin of the portion extends beyond the margin of the member A and this marginal portion of the member G Specification of Letters l atent.

constitutes the nail receiving member of the shingle. It is therefore flat in form and adapted to rest upon a roof board D, to which it may be secured by nails E. These shingles may be formed of galvanized iron Patented Nov. 14, 1916.

adapted to enter the groove formed by the members B and C of an adjacent shingle.

The shingles are preferably laid as illus-- 'trated in Fig. 1, with one set of opposing corners extending in straight lines up the surface of the roof at right angles to the ridge, and the otherset of opposing corners in lines parallel to the ridge, thus'sub-dividing the roof into sections which are substantially diamond shaped.

A substantially semi-cylindrical member H, preferably of the same material as the shingles is employed to cover the ridge. Each margin of this member is folded in- 'wardly along the line it and folded or doubled upon itself at h, from which fold it extends outwardly at an angle conforming to the pitch of the roof and constitutes a connecting flange I adapted to be secured to the roof boards'by nails 2'. In covering the roof with my improved shingle, this member H is first secured in a position covering the ridge with the flanges I nailed to the roof at each side of the ridge. The upper tier of shingles is then applied. The shingles in the upper tier 'are triangular in form, each comprising a member A corresponding to the lower half of the members A, the side margins of the triangular mem- .ber A being provided with the reversely bent marginal portions B, C. The upper margins of the triangular shingles A" are adapted to enter the groove formed by the reversely bent marginal portions of the member H.

After the shingles A are in position, they are nailed to the roof boards D, the nails E passing through the exposed portions of the members G. The second tier of shingles A will then be applied with their upper portions occupying the angular spaces between the downwardly extending apexes of the shingles A and their upwardly converging side margins entering the grooves between the members B and C of the reversely bent side margins of the shingles A. The

second tier of shingles will then be nailed" to the roof boards, the nails E passing through the exposed portions of the member C along the downwardly converging margins of the-respective shingles, after which the third tier of shingles will be applied with their upper'halt portions occupying the angles between the downwardly extending points of the second tier of shingles, the

straight edge margins of the shingles in the third tier entering the interlocking grooves in the lower margins of those of the second tier,

served that the structure is similar to that of the shingles shown in Figs. 1 and 2, except that the members A are hexagonal in form. These members have upwardly and downwardly extending apexes as in the other views, but they alsohave sides which extend substantially at right angles to the ridge. One of these side margins has an angular upwardly projecting portion L, which is elbowed at 1 and turned abruptly downwardly substantially in a vertical plane forming a wall lid. The opposing margin of the memher A is provided with a hook shaped flange N, adapted to engage in the angle be tween the members L and N of an adjacentshingle in thetier thus forming a water tight joint. In laying these shingles, the first tier will be laid at the ridge as demosses scribed with reference to the shingle illustrated in the other views,

1. A sheet metal shingle having a diamond shaped body portion adapted to be disposed upon the roof withtwo of its corners in a line substantially parallel with the ridge-and with the portion adjacent to the upper corner substantially flat, said body portion having flanges along its downwardly converging side margins which are reversely folded to form channels along said margins underneath the exposed surface of the body of the shingle, said flanges terminating at points sufiiciently above the lower corner of the body portion to permit the insertion of meeting lateral corners on adjacent shingles under the lower corner of said body portion with one side margin of each ad jacent shingle engaged in one of said channels, substantially as described.

2. A sheet metal shingle having a diamond shaped body portion adapted to be disposed upon the roof with two of its corners in a line substantially parallel with the ridge and with the portion adjacent to the upper corner substantially fiat, said body portion having flanges along its downwardly converging side margins which are reversely folded to form channels along said margins underneath the exposed surface of the body of the shingle, said flanges terminating at points sutliciently above the lower corner of the body portion to permit the insertion of meeting lateral corners on adjacent shingles under the lower corner or said body portion with one side margin of each adjacent shingle engaged in one of said channels the lower half of said body portion being pressed outwardly and forming 'a cavity between the body portion of the shingle and the roof, substantially as described.
